These tests were done on the CPU cores, not on the GPU. In every test I ran the A18 chip blew past Intel's Core 5 on GPU performance. There were a series of other benchmarks too, but the Hackaday article only highlights HPL as that was

Yeah, the first step is they realize pushing clocks is not the most important thing; second step is to apply that to other chips they make too! I want to see more desktop and server chips getting closer to Arm efficiency.

I run a number of other benchmarks for a better comparison (linked from my blog post: https://github.com/geerlingguy/sbc-reviews/issues/111 ). The Intel chip holds its own for multicore in less bursty workload

Not only that, the efficiency (FP64, HPL) is also beating all the M4/M3/M2/M1 systems I've tested besides the M4 Mac mini: https://github.com/geerlingguy/top500-benchmark#results I think the bigger

There are still big leaps, like their optical lattice clock that's sensitive to the gravitational difference caused by tidal effects on the earth's crust. It can detect gravitational differences of a few cm!

Sadly, no major miniaturization breakthroughs since. And those CSACs still eat up a lot of power (as do good OCXOs), making them rough for battery powered wearables.

Technically it will run on Pis — someone in my YouTube comments already has it going on top of basic Pi OS 13 (disabled NetworkManager and cloud-init to get it going). Someone else on Mastodon already has it running via a custom Pi 4 UEFI i

Yeah I clicked through and just see hundreds of "this account limits who can view their posts" messages.

Also a RAIDZ array (or just mdadm or BTRFS) with a cache in front can easily hit a couple GB/sec even on more consumer level hardware.

Apple used to even sell Xserve RAID and SAN software specifically to cater to the higher end users who needed fast networked storage (research, broadcast, media). They kinda hit a standstill on the networking side as they moved to the trash

Yeah the best option for cost is to buy one of the many TB4 to PCIe adapters on the market now (I've tried two), that are less than $100. They require external PSU power though, and they don't look nearly as nice on a desk.

The Mac Studio in most of my videos is my own workstation, purchased a while back. The 4 Mac Studio cluster I tested with Exo and Thunderbolt RDMA was a loaner cluster from Apple. There's no universe in which I could justify buying tha

Normal 4K editing workflows are fine with even 2.5 Gbps wired networking (wired to make latency like when scrubbing not-horrid)... 10 Gbps more necessary if editing ProRes RAW and doing multicam (4-8 streams simultaneously). I'm in a n

Yeah, raw RDMA is one thing, making sure other protocols can use it is another... hopefully Apple gets there, but right now SMB with RDMA is probably a tiny, tiny niche. I do wonder what Apple's custom-built servers are running for net

Projects like TenFourFox and PowerFox have ported modern FireFox to late PowerPC Macs running Mac OS X. And some of those Macs are at the bleeding edge (back then) of modern device support (PCIe, WiFi, etc.) so they can also run surprisingl

I've had the same struggle. There are some decent LED clocks with up to 1" displays (high), but any further and you get weird colors or glaringly-bright displays. The best options are expensive clock displays from like Time Machin

I've run it on a couple Macs, and it looks like one of the issues they're trying to fix is poor multi-core scaling that affected Geekbench 6 on bigger multicore systems (with 32, 64, or 128+ CPU cores). I'll hopefully get tim

The one feature I would love to see is WebSerial support, now that Firefox has it too.

I think it was a Maker's Muse video where I learned a ton about different 3D printable materials' shear strength when he was testing them in tiny battlebot-style robots. Some things feel unintuitive but I'm glad people take t

I'd love to be able to add 1U or 2U of blinkenlights to my rack, even if the pattern was completely random.

Yeah, and since it seems there's some competition there, the prices are decent. You can get milled metal, 3D prints, populated PCBs... crazy what you can do now and how quickly it can be turned around, if you are willing to pay. I wish

If you ever want to go into the KHz range, you could build a ship-scale platform to carry the antennas :D

Heh, welcome to RF; there are more rabbit holes to go down in domain specialty than I think there are grains of sand on a beach. I've gone down like... two. And I'm pretty overwhelmed. I think that's why a lot of EEs and deve

There are a few knockoff options too, which are not quite as nicely calibrated, but get the job done for much less than Fluke-level prices. Like the FOTRIC TD2. I think a few people have made homebrew versions too, like this one mentioned o
